Predator-prey interactions under near-future environmental change: The combined effects of increasing temperature and turbidity

这项工作的范围是调查水温和浊度的组合变化如何影响热带和温带淡水系统中的捕食者和猎物的相互作用。该项目将在布里斯托尔大学的温带系统中使用三刺刺鱼和雏蝇作为模型生物，在那里将使用计算机视觉跟踪软件(狩猎行为)和猎物死亡率来测量和分析捕食者的活动。在特立尼达，西印度群岛大学，野外和中观实验将测试孔雀鱼和它们的天敌--狗尾鱼--之间的相互作用。在这里，我还将收集现场的埃德纳样本，以评估人口数量及其与当地浑浊和温度的关系。最后，数据将被输入到一个模型中，以估计在不久的将来全球变暖对这些社区的影响。

The scope of the work is to investigate how combined water temperature and turbidity variations impact predator-prey interactions in freshwater systems, both tropical and temperate. The project will use three-spine sticklebacks and damsel flies as model organisms in the temperate system here at Bristol University, where predator's activity will be measured and analysed using computer vision tracking software (hunting behaviour) and prey mortality.In Trinidad, at the University of West Indies, both field based and mesocosm experiments will test the interactions of guppies and their natural predator, the pike cichlid. Here I will also collect eDNA samples from the field sites to assess population size and its relationship to local turbidity and temperature.Finally, data will be fed into a model to estimate the effects of global heating on these communities in near-future scenarios.
